Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically a lightweight column assembly. Background Technology
[0002] Currently, traditional vehicle pillar designs use 5mm thick, 200mm wide steel plates with flanged edges. This configuration not only complicates the structure but also increases the overall weight. For vehicles where lightweighting is a core objective, this bulky pillar design is no longer effective in meeting weight reduction needs and has become a burden in the vehicle lightweighting process.
[0003] For example, the Chinese patent documents “A Insert-Type Center Column Assembly” (patent application number: 202421806490.X) and “A Insert-Type Rear Column Assembly” (patent application number: 202421806475.5) both have the above-mentioned problems. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lightweight column assembly. This design abandons the structural limitations of traditional columns and achieves the lightweight requirements of the whole vehicle without reducing the overall strength.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lightweight column assembly, including a column body and a socket portion; the column body has a U-shaped cross-section, including a first base wall and two first side walls, the inner side of the first base wall is provided with at least one spring hook, and the top of the first base wall and the two first side walls is provided with an upper sealing plate; a lower sealing plate is provided near the lower end of the first base wall and the two first side walls, the lower sealing plate and the lower end of the first base wall and the two first side walls forming an installation space, and the upper end of the socket portion is inserted into the installation space.
[0006] A further improvement is that the column is made of P510L material, with a thickness of 4mm and a width of 130mm.

[0008] A further improvement is that the cross-section of the socket is a U-shaped structure adapted to the column structure, including a second base wall and two second side walls, and the second base wall is provided with waist holes in the vertical direction.
[0009] A further improvement is that the socket part also includes a panel, the lower end of which is flush with the lower ends of the two second side walls, the two sides of which are connected to the side edges of the two second side walls respectively, and the upper end of which extends into the column; a mounting hole is provided in the middle of the panel, and a nut corresponding to the mounting hole is welded to the inner side of the panel.
[0010] A further improvement is that the column serves as a pillar in the carriage, and two spring hooks are arranged side by side on the inner side of the first base wall.
[0011] A further improvement is that the column serves as the rear column of the carriage, and a spring hook is provided on the inner side of the first base wall, while another spring hook is provided on the outer side of one of the first side walls.
[0012] A further improvement is that the spring hook includes a back plate, a handle, a flip plate, a sliding plate, a hook body, and a connecting rod;

[0015] The slide plate is located between the flip plate and the mounting base and can slide along the axial direction of the side plate;
[0016] The hook is located above the back plate and is fixedly connected to the first base wall or the corresponding first side wall, and a hanging ring is attached to the hook.
[0017] The upper end of the connecting rod is connected to the hanging ring, and the lower end of the connecting rod passes through the flip plate and is connected to the sliding plate.
[0018] A further improvement is that the connecting rod is fitted with a return spring, and the two ends of the return spring abut against the flip plate and the sliding plate, respectively.
